Learned Knowledge: Agentic Mode

"""
Learned Knowledge: Agentic Mode
===============================
Learned Knowledge stores reusable insights that apply across users:
- Best practices discovered through use
- Domain-specific patterns
- Solutions to common problems

AGENTIC mode gives the agent explicit tools:
- search_learnings: Find relevant past knowledge
- save_learning: Store a new insight

The agent decides when to save and apply learnings.
